Now wifi can be found not only in offices, but has also expanded to housing, schools, and locations and other public facilities. Even so, there were doubts about the danger or safety of wifi on health.
Wifi is the latest technology using wireless local area networks (WLAN). Various other technological devices, such as cell phones and computers can be directly connected to wifi using radio waves, without having to plug in the cable first.
Radio Wave
When someone uses wifi or electronic equipment with a wifi device, it will be exposed to radio waves and some will be absorbed by the body. The concern that arises is the possibility of the influence of these radio waves on the damage to cells in the body, thus triggering the growth of cancer cells.
Until now, the scientifically proven effect of radio frequency exposure was an increase in body temperature, around 1 degree Celsius. However, it is only found in certain locations with very high exposure. In normal exposure, no increase in temperature is found which impacts on human health.
Although in some countries, wifi has also been linked to the risk of certain diseases, such as neurological disorders, heart disease, and cancer, but that is not sufficient reason and is not supported by strong evidence.
Radiation that is still tolerated
Wifi is classified as emitting non-ionizing radiation or low energy. Radiation is almost the same as that issued by cell phone signals, radio waves, television, microwaves, and ultraviolet (UV) radiation.
Furthermore, the signal from wifi and WLAN is very small, which is about 0.1 watt on computers and routers. This figure can still be accepted within the radiation limit issued by international organizations. In fact, radio waves emitted by wifi are lower compared to mobile phones.
The latest survey reveals, exposure to radio waves from the main base and public wireless technology is still far below the international limit allowed. Even so, the radiation exposure produced by wifi can also be influenced by other things, for example improper placement of a wifi router. Therefore, make sure to place the wifi router at least 20 centimeters from the house. This aims to reduce radiation exposure generated from wifi ..
Responding to speculations and tensions around this, the World Health Organization or World Health Organization (WHO), then conducts studies to obtain scientific evidence. Followed by the WHO statement, as long as the exposure is below the radio frequency that can be tolerated, which is 0-300 GHz, no known effect on the health of the human body. However, radio frequencies that exceed this limit are classified as unhealthy.
So, there is no doubt anymore, right? Because, until now fears of health problems due to wifi has not been scientifically proven. Come, surf again in cyberspace!
